How to add rows manually to a sheet where QUERY is already output from another sheet?

Question

Google Sheets

Applications are accepted in two ways: through GOOGLE FORM and manually.

3. Sheet/Sheets for intermediate data processing with or without consolidation
   
4. Sheet/Sheets to display processed data with or without consolidation
   

Consolidation in this sense means combining data through range notation { }or using scripts.
